About this course

This course will explain how to make sure each requirement is written in a manner that helps to assure a safe and effective user interface design, while also leaving room for designers and engineers to explore a range of design possibilities before converging on the optimal one. You will also learn about the extensive benefits of writing a comprehensive set of user interface requirements that can then serve to accelerate user interface design efforts and avoid time-consuming and expensive rework. Additionally, you will learn about the problems that can arise when user interface requirements are incomplete and incorrect, thereby failing to promote user interface design excellence. Upon completing the short course, you should be able to write your own, high-quality user interface requirements with confidence.

Within a 1-month period following the online course, you may schedule a 1-hour, complimentary consultation with the instructors to ask any specific and company-confidential questions about writing and implementing user interface requirements.

Meet the instructors

The instructors, who are co-authors of “User Interface Requirements for Medical Devices,” will walk through a structured process of turning wide ranging research findings into tight, verifiable user interface requirements.

Alexandria Trombley, lead human factors specialist

Alexandria Trombley is a lead human factors specialist with Emergo by UL’s Human Factors Research & Design team. She has been with the team since 2016. Trombley leads a variety of human factors projects, ranging from early-stage user research to HF validation testing and HFE reporting. She collaborates with clients to develop key human factors deliverables, including user profiles and use environment descriptions, known problems analyses, risk analyses, and HF validation reports. Trombley is also the co-author of the book: “User Interface Requirements for Medical Devices.” She holds a B.S. in Human Factors Engineering and an M.S. in Human Factors Engineering, both from Tufts University, and is a part-time lecturer at Tufts University, teaching a class on human factors analytical methods.

Erin Davis, associate research director
